A EuroMillions player has come forward to claim a £58million jackpot before the deadline.
The winning ticket from the March 17 draw was bought in South Ayrshire, Scotland.
A Camelot spokeswoman told the Mirror Online: "We can confirm that we are currently finalising the validation of a claim made on this prize and are in the process of arranging for payment to be made to the ticket-holder."
Once the ticket has been fully validated and the money paid out the winner can decide whether to go public or not.
The winning numbers for the draw were 5, 7, 8, 16 and 20 with Lucky Stars 2 and 12.
The Mirror reported last night that if the prize wasn't claimed by midnight it would have been lost forever.
And the National Lottery previously urged the mystery ticket-holder to come forward at the end of March.
It is unclear whether this claim came right before the deadline or was an existing claim still being processed.
Winners have 180 days to come forward.
The huge prize of £57,869,670 was set to be added to National Lottery Project charity funds if it was not claimed in time.
The jackpot would have been the largest unclaimed one.
Now, according to the National Lottery website the highest unclaimed jackpot is £1m.
The biggest EuroMillions winners in the UK are from Scotland.
Colin and Chris Weir, from Largs in Ayrshire, scooped £161m in 2011.
The husband and wife, who have since divorced, were catapulted into the Sunday Times Rich List above Beatle Ringo Starr and Sir Tom Jones with their £161million win.
Married for 30 years and with two children, they bought a mansion - which they later upgraded to a bigger one nearby - and a fleet of cars.
Psychiatric nurse Mrs Weir, 55, and Mr Weir, 64, who worked as a TV cameraman and studio manager for 23 years, have made three £1million donations to the SNP since their win.
Football fan Mr Weir also helped refurbish Largs Thistle’s ground and gave more than £1million to Partick Thistle so they could set up a youth academy and clear debts.
A spokesman for Camelot said: "As with all major prizes, the claim goes through a rigorous validation process to ensure the prize can be paid under our game rules.
"If a valid claim is not received, the prize money is passed to good causes."
